Sig Sauer Hexium 5.56mm TI Suppressor 5.56mm Titanium Hub Taper Direct Mount 1/2"-28

The Sig Sauer Hexium 5.56mm TI suppressor is a titanium-core rifle suppressor built for shooters who demand both performance and durability on the range or in the field. This 5.56 NATO suppressor uses Sig Sauer's advanced 3D printing and internal geometry design to deliver low back pressure and clean, quiet sound signature across your platform. With a direct-thread 1/2"-28 hub taper mount, it threads straight onto your muzzle for a rock-solid, easy install—no special adapters or quick-detach hardware needed.

Built from titanium, the Hexium is engineered to handle serious use without excess weight. The external hexagonal pattern and black Cerakote finish strike a balance between tactical aesthetics and real-world durability. An accessory mounting system at the front end gives you modularity if you want to add or swap components down the road. Whether you're running a precision rifle, an AR-15 upper, or any platform with a 1/2"-28 threaded muzzle, the Hexium is designed to integrate seamlessly while keeping gas blowback and felt recoil in check.

Sig Sauer backed this suppressor with engineering rigor—computer-modeled baffles, state-of-the-art test equipment, and real-world validation. If you shoot enough to care about sound signature consistency, back pressure effects on your gun's reliability, or long-term durability, the Hexium's titanium construction and refined internal design make it a serious choice for serious shooters.

Frequently Asked Questions

What rifles is this 5.56 suppressor compatible with?

The Hexium 5.56mm is compatible with any rifle or upper receiver with a 1/2"-28 threaded muzzle, including most AR-15s, modern sporting rifles, and precision rifles chambered in 5.56 NATO or .223 Remington. The direct-thread mount screws on—no quick-detach adapter needed.

How much does it weigh and will it affect my rifle's balance?

The titanium Hexium weighs 11 oz, making it one of the lighter options in its class. Most shooters find this weight minimal relative to the sound reduction benefit, though individual perception varies with your rifle and barrel setup.

What does "low back pressure" mean for my gun?

Low back pressure means the suppressor's internal design minimizes the amount of gas that gets pushed backward into your rifle's action. This helps your gun cycle reliably and reduces felt recoil, which is especially valuable in semi-automatic firearms where excess gas can cause reliability issues or harsh cycling.

What's the modular end cap system?

The Hexium has an accessory mounting system at its front end, which allows you to add or change end cap components if Sig Sauer offers compatible accessories. This gives your suppressor some flexibility for future upgrades or configuration changes.
